Definitions
- the invention relates to a drainage mat for removing the surface water for horizontal, vertical or sloping surfaces, consisting of a Profile layer with an interrupted cross-section, the spaces between which flow away of the water and a fleece on the top, which punctually with the Profile layer is connected and prevents the penetration of soil.
- drainage pipes have depending on the application a diameter of 5 - 20 and more cm, providing the necessary mobility obtained in that the drainage tube is designed as a flexible tube that is at a distance has arranged annular stiffening parts.
- These are usually made of yellow plastic manufactured drainage pipes require a separate installation, because only then necessary inflow can be secured. Appropriate trenches are dug, which are then partially filled with gravel, with the drainage pipe in the Gravel is embedded. The effort involved is considerable.
- Drainage pipes are known which are as uniform and as possible ensure surface drainage of the water.
- Such drain elements exist from an interrupted cross section several mm thick, which, for example is formed by pimples.
- Such drainage mats therefore have the necessary strength and also withstand the considerable pressure that arises when the drainage mat is on material is still being deposited. This is the case, for example, if one Landfill is covered with drainage mats and then to produce a Green area soil is deposited on the mat.
- the broken cross section of the Drainage mat is used to allow the water to drain away in the spaces.
- a filter fleece can be arranged above this, which serves to keep the soil is held back by the actual mat and does not penetrate into the gaps can. At the same time, the filter fleece ensures due to its water permeability, that the excess water gets into the gaps and flows off can.
- the drainage mats are several mm thick and are relatively rigid, since they are designed to absorb significant loads. They then slip slightly on the surface. With those used for the production Plastics remain the contact areas between the drainage mat and the the surface to be covered is too smooth for sufficient grip to be achieved could.
- the drainage mats are too narrow to be able to be transported Rolls of webs rolled up, which, when subsequently laid, result in partial webs must be placed on top of each other to achieve the necessary sealing, causing wastage of material, leaks and there are significant shifts.
- the object of the invention is to create a drainage mat which guarantees good adhesion to the surface and overall this and reliably covers without the risk of leaks.
- the drainage mat on the bottom has a large number of individual points and / or threads protruding above them and that the partial overlap of at least on one outside of the drainage mat arranged two adjacent drainage mats allowing strips without profiling are.
- the threads arranged below the profile layer ensure that can no longer move the drainage mats on the ground because of the the arrangement of the threads prevailing frictional forces prevent this. Also uneven, hilly or sloping surfaces can be covered effectively. A rough, non-slip surface is created on the underside of the drainage mat, which in particular is achieved by applying the threads on the underside.
- the threads can in a technically relatively easy to implement manner, without specifying a certain structure and precision can be applied.
- the even layer may also be arranged, which, however would not have such favorable friction properties.
- the strips are advantageously formed from the same material as the profile layer itself and thus with regard to the mechanical and building physics Features a homogeneous drainage mat.
- the stripes can for example, can also be welded to the drainage mat later, more cost-effectively but it is to produce drainage mat and strips in one step.
- the invention provides that the strips of two adjacent webs of Drainage mats that enable their thermal or mechanical connection Width, preferably 5 - 10 cm.
- the strips of adjacent webs will be so placed on top of each other and then welded or otherwise connected to each other. This can be independent of the formation of the subsurface and its inclination happen. Since it is possible in principle, a strip according to the invention to be placed either on one or both sides of the drainage mat, overlap either the stripes over each other or the single stripe overlaps the neighboring one Drainage mat in the profile area.
- the simplest design of the strips according to the invention provides that the Strips have a reduced thickness and a flat surface. Furthermore, can such a strip also has a roughened surface or is otherwise profiled his.
- the threads can be in one be applied such that an additional layer is created.
- the invention provides for a particularly non-slip drainage mat before that the dots and / or threads have a rough or textured surface exhibit. Not only by the arrangement of the threads, but also by their formation and surface should improve the friction properties of the drainage mat become.
- the material used for this purpose is preferably high density polyethylene used. However, it is also possible to use other plastics for this purpose, however Polyethylene has proven to be special in terms of the required friction properties proven suitable.
- a preferred embodiment of the invention provides that the profile layer is formed by deep-drawn knobs and connecting webs.
- the profile layer is advantageously made of made of a material so that no leaks can occur.
- the deep-drawn knobs of the profile layer provide sufficient strength, so that there is also sufficient stability.
- the top of the drainage mat is designed so that the fleece is made of plastic manufactured and glued or thermally attached to the tips of the knobs is. Instead of a fleece made of plastic, you can also use a natural one Fibers produced material can be arranged.
- the threads are expediently from one to the underside of the drainage mat sprayed hot melt adhesive formed on polyolefin basis. This hot melt adhesive is first applied to the underside of the drainage mat during manufacture, then the threads.
- the threads have particularly good adhesion to the drainage mat and to the substrate.
- the invention is characterized in particular by the fact that a drainage mat created, which cannot slip under normal circumstances and one ensures a secure hold on the surface, while at the same time being reliable Coverage is given without the risk of leaks.
- a drainage mat created which cannot slip under normal circumstances and one ensures a secure hold on the surface, while at the same time being reliable Coverage is given without the risk of leaks.
- This is due to one made of polyethylene on the underside of the drainage mat Threads that significantly reduce the frictional properties of the bottom of the drainage mat improve.
- this is due to that on the outer sides of the neighboring ones Strips attached to drainage mats, which overlap each other and such are easy and safe to weld.
- FIG. 1 shows a cross-sectional view of a landfill.
- the substances 22 to be deposited upset are then covered with the drainage mat 1 according to the invention.
- the drainage mat 1 is constructed in such a way that by the top of it arranged fleece flowing water can drain through the spaces. On this way the landfill is constantly drained. Above the drainage mat 1 can Soil 20 are applied to cover the deposited substances and the Reintegrate landfill into the landscape. The upcoming in the ground 20 Thanks to the arrangement of the drainage mat 1, water cannot reach the area to be deposited Substances 22 arrive, but is removed, collected and the receiving water fed.
- the structure of the drainage mat 1 is shown in FIG. 2.
- the profile layer 4 which is formed from deep-drawn knobs 6.
- This embodiment forms the considerable advantage that the profile layer 4 consists of only one, homogeneous Material is made, which significantly reduces the risk of leaks.
- the formation of the knobs 6 results in spaces 15 through which the water discharged from the soil 20 can flow off well.
- the fleece 7 arranged in the drainage mat 1 prevents that above the drainage mat 1 located material gets into the spaces 15 and clogged and thus preventing the water from flowing out.
- This Threads 8 give the underside 3 of the drainage mat 1 an uneven and rough Structure, so that a much better frictional connection between the bottom 3 and the layers below are reached.
- the invention Drainage mat 1 not only on horizontal, but also uneven inclined or apply hilly surfaces without the risk of slipping.
- FIG. 3 Here is an excerpt from a drainage mat 1 shown in bottom view. The rough one is clearly visible Structure that is given to the underside 3 by the threads 8. Their application on the bottom 3 is also relatively simple because the threads 8 in none certain structure or orientation, but can be sprayed on without great precision can. As a result, the process for producing the embodiment according to the invention is uncomplicated.
- the polyolefin-based hot melt adhesive is melted and then sprayed on with pressure so that it is in the form of threads 8 in more random adheres to the underside 3 of the drainage mat 1 in a targeted manner.
- threads 8 are applied to the underside 3 of the drainage mat 1. Their effect could also be alternative or complementary through the application can be reached from individual points of any size.
- FIG. 4 shows an average of two webs 11 and 12 arranged side by side. Until now, these had to be partially overlaid in their full thickness or very dense placed side by side. This led to leaks or unnecessary waste of material. In the arrangement of the strips 14 on the outside according to the invention 9, however, a reliable seal is achieved. The strips 14 can are now connected thermally or mechanically, leaks occur no longer, which ultimately creates a large sealing or drainage area.
- FIG. 4 shows the embodiment with one arranged on the outside 9 Strip 14, which in this case is assigned to web 11 and overlaps web 12.
- the strip 14 overlap the web 11 and the strip 14 'of the web 12. There are therefore webs 11 on both sides, 12 strips 14, 14 'arranged, which are now thermally or mechanically connected become.
